GRATE.

SPECIFICATION forming part of Letters Patent No.-633,332, dated September 19, 1899.

Application filed February 8, 1899.

grates; and it consists in thenovel combination and arrangement of parts, as will be" hereinafter more particularly described and I claimed.

In the drawings, Figure 1 is a vertical longitudinal sectional View of an ordinary firebox, showing my inventionproperlyarranged therein; and Fig. 2 is a'vertical longitudinal section taken onthe line a: x of Fig. 1, showing one of the grate-bars and its accompanying parts.

The object of my invention is to construct a grate in such a manner that the coal or other f fuel when placed upon the same will not only 5 be equally distributed and fed along the entire grate, but will arrange the fuel in such a 5 manner that all the products of combustion i will be completely consumed, and, further,automatically fed from the mouth of the fire-box .along the entire grate.

Briefly stated,the invention principallyconsists of grate-bars of suitable construction, tframes or supports located and secured to the opposite sides of the fire-box and provided with bearings which are arranged at an in- 'cline from the mouth of said fire-box and :adapted to movab'l'y receive the opposite ends *of the shafts comprising a part of the gratebars, a bell-crank lever pivoted to one of said supports adjacent to the front of the fire-box and adapted to be operated by hand, a bar to which the lower extensions of the grate-bars are movably secured, the upper end of which is pivotally attached to said bell-crank lever, whereby the grate-bars are simultaneously titled or operated by the movementof said lever, and in other details in the construction, as will hereinafter be more fully described.

Referring to the drawings, 1 represents a fire-box of the well-known construction, with- Serial No. 704,917. (No model.)

in which my invention is located, and secured to theopposite sides of the same are two supports 2, which are arranged at an incline from the mouth or feeding end of the fire-box, the upper ends of which are secured to the opposite sides of the said fire-box and having their opposite ends provided with legs 3, which are adapted to rest upon the-bottom of the firebox or ash-pit. Located between the said supports adjacent to the lower ends of the same is secured a connecting-brace 4, which operates to hold that portion of the supports in their proper position in respect to one another.

lhe supports 2 are provided with bearings 5, which are arranged along the length of said supports, and consequently at an angle also, which are adapted to receive the opposite projecting ends 6 of the grate-bars 7, whereby the latter are not only arranged at an incline, but are pivotally secured within the lire-box.

Depending from each of the grate-bars 7 is i an arm 8, havinga right-angular extension 9,

the latter being adapted to be received loosely by openings formed along the bar 10, which operates to movably connect all of the gratebars, and passing through each of the extensions 9 is a pin 11, which holds the bar 10 in its proper position.

Pivotally secured to the side of one of the supports 2 adjacent to the feedingend of the fire-box is a bell-crank lever 12, the short arm of which is movably connected to the upper end of the bar 10 and having its longarm extending a suitable distance outside of the fire-box and operating as a hand-lever for manipulating the grate-bars when it is desired to feed the coal or other fuel from the feeding end of the fire-box along or throughout the entire length of the grate.

In order to properly carry out my invention and cause the fuel to remain aproper'length of time upon the grate-bars at an incline, the upper surfaces of said bars are fiat, as shown at 13, whereby the fuel is held in astationary position for a certain length of time in order to properly consume all of the products of combustion, and forming a continuation of the fiat upper surfaces of the grate-bars are curved surfaces 14, which permit the fuel that has previously rested upon the flat surfaces 13 to readily pass off the grate-bar to its adjacent lower one when the hand-lever 12 is raised in the position shown in dotted lines, Fig. 1, whereby all of the flat surfaces 13 will be on a line with one another, but at an incline, causing the fuel to be properly fed or moved toward the delivery end of the grate, in which instance the said fuel will have been completely consumed, the ashes being deposited in the ash-pit located below the grate.

In carrying out my invention any form of grate may beemployed and, if found desirable, may be made up in sections, whereby should any portion of the bar become destroyed it may be easily replaced without removing the entire grate bar; but in any event the upper surfaces of said bars must be of such a nature as to properlysupport the fuel when the grate-bars are in their normal position.

By referring to Fig.1 it will be seen that the lower grate-bar is somewhat differently constructed from the upperor reinainingones and is provided with a fiat surface 15, which is arranged at an incline when said upper or remaining bars are in their normal position, which operates to allow the ashes to readily slide off of the same into the ash-pit below, and, further, when the said upper bars are tilted the said lower grate-bar will assume a perpendicular position, which more effectually operates to throw off the ashes into the ash-pit, as the said ashes pass from the remaining grate-bars in the operation of shaking the grate for feeding the fuel to the rear of the fire-box. I

In feeding the grate the fuel is deposited upon the plate 16 only, which is located at the mouth of the fire-box, and from said plate the said fuel will properly drop upon the grate and the fuel fed along the entire length of the same, as may be desired, by operating the hand-lever in the manner previously described.

Having fully described my invention, what I claim is- In combination with a fire-box, of an inclined supportlocated therein, grate-bars pivotally mounted upon said support, having upper flat surfaces upon which the fuel is adapted to rest, and curved surfaces forminga continuation of said flat surfaces, whereby when the said bars are tilted, the said flat surfaces will be inclined and on a plane with one another, a lower grate-bar having an upper flat surface, which is in an inclined position when the upper bars are in their normal position, and caused to assume a perpendicular position when the bars are tilted for properly directing the ashes to the pit below, and means for operating said bars simultaneously, as and for the purpose described.

In testimony whereof I aifix my signature in presence of two witnesses.
